摘要
为解决干旱半干旱地区造林成活率低的问题,通过使用蓄水渗膜材料进行造林试验,与未使用蓄水渗膜袋造林进行比较,调查生长情况。结果表明,使用蓄水渗膜袋造林明显好于对照,造林成活率、苗木生长量与对照有显著差异。在乌兰布和沙漠,测量使用蓄水渗膜袋和未使用蓄水渗膜袋方式,各个不同深度土层的土壤含水量、蓄水渗膜袋埋放处含水量均有提高。
In order to increase the survival rate of afforestation in arid and semi-arid area, afforestation experiment with water storage and controlled-release film to inquire into the state of growth which was in comparison with that without it showed the obvious differences in survival rate of afforestation and growth (hight and diameter) and that the experiment with it was obviously better than without it. In the soil of different depths, the water storage increased by using the water storage and controlled-release film which derived from the experiment in Wulanbuhe desert.
